Thank you for viewing. These are special tabi (split-toe socks) used in power line construction. Size: 25.5cm Although new and unused, the inner fabric has turned pink in places due to improper storage. I investigated and found it was yeast (red mold). It seems possible to remove it with baking soda, lukewarm water, etc. The extent of the pink discoloration may be difficult to see, so please check the images. Only those who understand these points, please.
